2:2+128382:228+832882+821818-2828+1234•71

To solve the expression \(2:2 + 128382:228 + 832882 + 821818 - 2828 + 1234 \cdot 71\), we need to follow the proper order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction).

Let's break this down step by step.

1. Division:

   • \(2:2 = 1\)
   • \(128382:228 \approx 563.68\) (exactly if you do the division)

2. Multiplication:

   • \(1234 \cdot 71 = 87614\)

Now we have: \[1 + 563.68 + 832882 + 821818 - 2828 + 87614\]

3. Addition and Subtraction:

   • First, sum the values step by step:

   \[ 1 + 563.68 = 564.68 \]

   \[ 564.68 + 832882 = 833446.68 \]

   \[ 833446.68 + 821818 = 1656264.68 \]

   \[ 1656264.68 - 2828 = 1653436.68 \]

   \[ 1653436.68 + 87614 = 1741050.68 \]

The final result is approximately: \[ \boxed{1741050.68} \]
